Do I need an air fryer? Hmmm
What benefits has this over the oven?
basically it cooks in nearly half the time, or faster as I do not bother preheating, so if I come in the door it is faster though the time in the oven might not be half. So would do say chicken nuggets in 10mins from proper deep freeze with no preheat. You can set the timer like a microwave so I would head off to the shops with it on, when it turns off it does not retain as much heat as an oven so just keeps food warm while an oven would continue cooking quite a bit.
I would want a bigger one though, the standard size barely does a single person.
More energy efficient than a standard oven.
Many prefer the food out of them.
